Low Sperm Count (Oligospermia) Treatment at Yaal Fertility Centre, Chennai

A number of distinct problems can lower a sperm count or reduce motility, and identifying which one is at play changes what is done about it.

Varicocele — enlarged veins within the scrotum — is one of the most common correctable causes, thought to raise testicular temperature in a way that impairs sperm production and motility. It is often, though not always, treatable with a relatively minor surgical procedure.

Hormonal imbalances — low testosterone, or abnormalities in FSH, LH, prolactin, or thyroid function — can suppress sperm production directly and are among the more medically treatable causes.

Lifestyle and environmental factors are a large and often underestimated category: smoking, heavy alcohol use, obesity, anabolic steroid use, prolonged heat exposure (frequent hot baths, saunas, laptops on the lap), and certain occupational exposures to toxins or heavy metals can all reduce count and motility.

Genetic factors can affect sperm production in ways that range from mild to severe, and are more often investigated when the count is very low rather than mildly reduced.

Infection — current or past infection of the reproductive tract — can temporarily or, less often, persistently affect sperm production and motility.

In some men, no clear cause is found despite thorough investigation, and the finding is described as idiopathic. This does not mean nothing can be done — many of the same lifestyle and, where relevant, assisted reproduction options still apply.

A semen analysis measures several parameters together, and the pattern across them matters more than any single figure in isolation. The main parameters are:

• Concentration (count) — the number of sperm present per millilitre of semen.
• Motility — the proportion of sperm that are moving, and how well they move (progressive versus non-progressive movement).
• Morphology — the proportion of sperm that are normally shaped.
• Volume — the total amount of semen in the sample.

Laboratories compare these figures against reference ranges to classify a result as within or below the expected range. It is important to know that these reference ranges are periodically revised by international bodies as more population data becomes available, and a result described as “low” against one set of reference ranges may be interpreted differently against an updated set. For this reason, we do not state specific numeric thresholds on this page — your report will be interpreted against the current reference ranges used by our laboratory, and explained to you directly by your doctor rather than left to a generic number.

Because results can vary from sample to sample due to illness, fever, stress, or a short abstinence period, a single report showing a low count or reduced motility is never treated as a final diagnosis. It is standard practice to repeat the analysis before drawing any conclusion.

Where a specific, correctable cause is identified, treatment is directed at it directly: surgical correction of a varicocele, medication for a hormonal imbalance, or antibiotics for an active infection. Where no single correctable cause is found, or alongside treatment of one that is, lifestyle change is the next most valuable lever.

The changes most consistently associated with improved sperm parameters include stopping smoking, reducing alcohol intake, achieving a healthier body weight, stopping anabolic steroid use, avoiding prolonged heat exposure, and reviewing any medications that may be affecting sperm production with your doctor. None of these produce an overnight change: sperm take roughly three months to develop, so the effect of any change made today will only be visible in a semen analysis around three months from now, and the same three-month window applies to any improvement following varicocele surgery.

These measures can meaningfully improve borderline parameters, and in some couples that improvement is enough to make natural conception or IUI realistic where it previously was not. They are less likely to overcome a severe reduction in count, a significant genetic cause, or a very low motility that has not responded to an identified and treated cause — in which case assisted reproduction becomes the more realistic path.

Not every low count or motility finding requires ICSI. Where the reduction is mild and the female partner has no significant fertility factor of her own, natural conception or IUI (intrauterine insemination, which concentrates the best-moving sperm and places them directly in the uterus) may remain realistic, particularly after lifestyle optimisation or treatment of an identified cause.

ICSI becomes the recommended path when the count or motility is severe enough that the number of sperm capable of reaching and fertilising an egg unaided is too low for natural conception or IUI to be a realistic strategy, or when time is a significant factor — for example, where the female partner’s age or ovarian reserve means that repeated unsuccessful attempts at a lower-intensity treatment carry a real cost. Because ICSI involves injecting a single selected sperm directly into each egg, it requires only one viable sperm per egg retrieved, which is precisely why it remains effective even where the sperm available are very few.

In the rare situation where a man with a previously low but present count is found on a later sample to have no sperm at all in the ejaculate, or where the couple’s doctor recommends investigating whether more sperm can be found directly in the testicular tissue, surgical sperm retrieval (TESA or micro-TESE) may be discussed — this is covered in detail on our dedicated page.
